摘　　要：对聚焦光束通过有一定外加电场ＢａＴｉＯ３晶体时的自陷现象进行了理论分析，发现在正切割晶体中观察空间孤子是不合适的，因仅利用了很微小的电光系数γ３３。对异型切割情况进行了讨论，给出了维持光束自陷的外加电场范围和实际观察的最佳角度。In this paper, self trapping of a focused optical beam through BaTiO 3 with some external field has been theoretically studied. We find that it is unsuitable for observation of the spatial solitons in conventional cut crystals, in which only the small electro optical coefficent γ 33 is useful. By invesgating self trapping in special cut crystals, the range of the external field for self trapping of the beam and the optimal angle have been given.
